Just back from the vet. One word...

Fleas

😕

@jerry You or the dog?
@noxubell my cat, who was in to have a glucose sensor installed. but I am pretty sure he got the fleas from one of the other cats or the dog, so we are having to treat them all as if they have them
@jerry small consolation but it’s only fleas. I just learned a couple of days ago of “Machiavellian microbes” when listening to "The Disappearing Spoon" podcast. Those are frightening. https://www.sciencehistory.org/stories/disappearing-pod/machiavellian-microbes/
Machiavellian Microbes

Parasites can force animals to do nefarious things by manipulating their minds—including, uncomfortably, the minds of human beings.
